I just ran: 

uname -r

and this came up: 

4.4.0-53-generic

Then I did: 

sudo apt upgrade

the output was:

The following NEW packages will be installed:
  linux-headers-4.4.0-57 linux-headers-4.4.0-57-generic linux-image-4.4.0-57-generic linux-image-extra-4.4.0-57-generic

But when I run

uname -r

I still get 

4.4.0-53-generic

What should I do?

    Have you rebooted after installing the new kernel? If not, there's your answer. The newer kernel will be used in the subsequent sessions only. –  Dec 23 '16 at 16:04

After your first uname -r it listed 4.4.0-53 as the kernel version you last booted with.

When you did sudo apt upgrade it offered to update your disk with newer kernel 4.4.0-57 but you must select Y to upgrade it on disk. You did not say if you did this or not.

When you typed uname -r a second time it still shows 4.4.0-53 as the kernel you booted with because you haven't rebooted yet.

Anyways... Do the upgrade and select Y and then reboot to get the newest kernel booted into RAM and virtual directories /proc, /sys, etc.

apt-get upgrade is restricted to the case where packages are to be replaced by newer versions.

but in your case there are packages be additions, so you should use apt-get dist-upgrade.
For example, 'linux-image-generic- package will update by 'linux-image-4.4.0-57-generic'.

    Can you please summarize that link into your answer. A simple [edit] would suffice. Be sure to link back to your source if appropriate – Kaz Wolfe Dec 23 '16 at 17:27
  • @KazWolfe Good suggestion, I added a description just now. –  Dec 23 '16 at 17:46
  • Now I do: uname -r and here is the result: 4.4.0-57-generic. But Computer is still super slow. I do alt + tab a lot to switch between programs and it takes forever. and I am nor running anything heavy. Any Idea? – Ken Sandoval Dec 23 '16 at 18:57
  • @KenSandoval Well.. the kernel does not significantly affect system performance. First of all, try to check the cpu usage of each process. –  Dec 23 '16 at 23:05
  • I've done that. and it is just internet browsing. for example, if I use chrome, I then, . I switch to firefox and is slow also then switch to chromium and is the same. . How to improve internet browsing performance then?. (ISP speed is fine and I connect with ethernet cable. I have 10 MB speed. – Ken Sandoval Dec 24 '16 at 18:48
